SEATTLE (AP), Dec 10 - Diego was a model passenger, sitting quietly with seat belt buckled, never fidgeting. But it was the huge, unblinking eyes that made a Washington state trooper suspicious.

The state patrol says troopers were stationed Nov. 29 along an Interstate 405 onramp, pulling over people who were driving in the high occupancy lane with only one person in the car. That's when the odd ``passenger'' drew one trooper's notice.

The patrol says the trooper stopped the car and found the driver had placed a stuffed Diego doll from the Nickelodeon children's show ``Go, Diego, Go!'' in the front passenger seat. The unidentified driver said he was late for work so he drove off with his daughter's doll so he could use the HOV lane.
